Embodiment Construction

[0027] The present invention relates to a method for building a ship using a floating dock, said method comprising the following process steps:

[0028] Step 1. Add a certain amount of ballast water in advance in the ballast tank of the floating dock, and the amount of the ballast water is greater than the total weight of the following total sections.

[0029] Step 2. Under the condition of keeping the ballast water volume constant, draw a straight line on the left and right inner dock walls of the floating dock as the deflection control line of the floating dock. The two deflection control lines are 1.4 to 1.6 meters away from the pontoon deck and parallel to each other, and the center line of the new ship is plotted on the pontoon deck of the floating dock as the control line of the new ship center line.

[0030] Step 3. Combine the new ship sections into several general sections on the site of the general group, such as figure 1 . And plot the center line and height posit...

Abstract

The invention relates to a shipbuilding method by utilizing a floating dock, which comprises the following process steps: 1) adding a certain amount of ballast water in a ballast tank of the floating dock in advance; 2) respectively assigning straight lines on the left inner dock wall and the right inner dock wall of the floating dock as deflection control lines of the floating dock; 3) joining sections of a new ship to form a plurality of blocks on an assembly site, and hanging the first block into the floating dock; 4) pumping out the ballast water in the ballast tank which corresponds to the first block; 5) using a three-dimensional adjusting machine for adjusting the front, the back, the left, the right and the height positions of the first block; 6) hanging the second block into the floating dock, and then repeating the fourth step; 7) taking the central line and the height position line assigned on the first block as joining references of the second block; and 8) repeating the operation to join the second block and continuing the operation in such way till completing the joining of all the blocks. The method can solve the problems of determination of the reference lines of the ship and fast adjustment and positioning of the blocks of the new ship during the shipbuilding in the floating dock.

Description

(1) Technical field [0001] The invention relates to a method for building a ship using a floating dock for ship repair. It belongs to the technical field of shipbuilding. (2) Background technology [0002] Slipway and dry dock are ship closing and launching facilities, which are widely used for new shipbuilding; floating dock and dry dock are widely used for ship repair. These are important facilities of the shipyard, with large investment and long cycle. [0003] With the rapid expansion of the demand for new ships in the world, and the new shipbuilding facilities cannot be rapidly increased in the short term, in order to alleviate the contradiction between supply and demand, various shipyards have transformed the dry docks used for ship repairs and used them for ship building, but most ship repairs use floating docks . If the floating dock can also be used for shipbuilding, the sharing of ship repairing and shipbuilding resources can be realized to a greater extent, and...
